TENSION DEVICE FOR SILK-SPINNING MACHINES.

SPECIFICATION forming part of Letters Patent No. 340,631, dated April 27, 1886.

Application filed May 19, 1884.

To CLZZ whom it may concern:

Be it known that 1, GEORGE SINGLETON, a citizen of the United States, residing at Dover, Morris county, State of New Jersey, have invented a new and useful Improvement in Tension Devices for Silk-Spinning Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The object of my invention is to provide a tension device for silk spinning machines, wherein the strands are kept under a uniform tension during their passage through the machine, and also a device for preserving the tension when the machine is suddenly stopped or when its speed is suddenlyincreased. These objects I attain by the construction shown,

which will be fully explained, and pointed out in the claims.

Figure l of the drawings is a perspective view of a portion of a silk-spinning machine having my invention attached thereto. Fig. 2 is a detached view of bracketrolls, guidewire, and a portion of the rail, the rolls being in section. Fig. 3 is a plan of the same, and Fig. 4 is a transverse sectional elevation of the machine on a line slightly at the right of the thread shown in Fig. 1.

The machine made use of in the application of my invention is provided with a spindle, b, driving'cylinder b", band'b, drivingroll a, traverse-bar 0*, and guide-rods 0 all as is usual in this class of machines, and need not be further described herein.

B represents an angle-bracket, the foot of which bracket is secured to the rail d by means of a screw, (1, that passes through the foot of the-bracket, and which screws in the rail (1, and which gives ample support to the bracket, to hold the same in the several posi-- tions in which the same may be placed for purposes of tension. In the projecting part B* of the bracket is suitably arranged and se cured a pin, B. On the pin B are arranged tension-rolls B and B, the inner ends of which are dished centrally, while their outer circumference is slightly rounded off, which construction permits the roll B to jam against the roll B, and thereby place tension on the most delicate strand when the stud B is in elined at an angle with the horizon. The yokeshaped guide 0 is also secured suitably in the arm B of the bracket B, which gives ample support to the guide as well as to the pin B, to carry and support the rolls B B. At a suitable distance below the tensioirrolls, and journaled in the arm a, is a rod, I. The rod F is provided with a handle, F, and has arranged thereon a coil, f, having a hook, j, which hook rests on a rod, f, which rod is connected to the rod F by links f and is operated thereby. In the outer end of the arm a is secured a rod, f, over which the spun thread passes to the rolls B B The machine is supposed to be in motion,

is taken from the bobbin 0 upward to and partly over the rod f, through the hook f up to the guide 0, to and between parts 6 of said guide, to and between the tension-rolls B B", and over the usual guide and traverse bars, 0' c up to the receivingbobbin c, which, being in rotation, winds the spun fiber on the same under the influence of the usual traverse mechanism. The tension-roll B", owing to the incline given to the pin B, tends continually in the direction of the roll B and into engagement with the strand 0, and puts the same under tension. The tension may be increased or diminished by simply changing the position of the bracket B on the rail d by means of the screw (1, which screw is adapted to hold the bracket in its several positions where the same may be placed for purposes of tension. It will be understood that when the pin B is placed at an increasedincline it throws more of the weight of the roll B on the strand 0, which will increase the tension of the strand accordingly, and the opposite will be the case when the pin is placed 'upon a less angle or incline. The rounded form of the guide U, as shown at 0, permits the strand to enter the guide and be guided by the same between the tension rolls without injury. \Vhen the machine is to be brought to a sudden standstill, the handle F is pulled forward, which action, by means of links f depresses the rodf, while the coil f", which is in tension, causes the hook f to follow the rod f, and carry with it in the hooks descent the strand 0, which action keeps the strand taut,

and prevents kinks and twisting of the strand and the operation is as follows: The strand 0 0. WVhen the machine is started, the handle slide over pin B, for tension, substantially as is pushed back gradually until the rod f 1's and for the purpose set forth. raised in position with the hook, strand, 8:0. 2.
